PDB_SELCHAIN(1)

💖 PDB_SELCHAIN 💖

okay bestie, welcome to pdb_selchain, the manual page for pdb_selchain 2.5.1 ✨ it's giving chain-picker energy and honestly? iconic 🎀

---

🌸 NAME 🌸

pdb_selchain — like, the girl who extracts chains for you. that's it, that's the job 💅

---

✨ DESCRIPTION ✨

so here's the vibe: pdb_selchain extracts one or more chains from a PDB file. that's the whole personality 🦋

and listen — you must provide at least one chain identifier. no chain id, no service. if you run it with nothing it will just say:

pdb_selchain You must provide at least one chain identifier

so don't do that 🙈 give the girl a chain, she'll give you a file.

🫶 Usage:

python pdb_selchain.py -<chain id> <pdb file>

that's the shape of it, bestie — dash, then the chain id(s), then the PDB file. easy 💖

🌈 Example:

selecting just the one chain:

python pdb_selchain.py -C 1CTF.pdb
       # selects chain C

selecting a lil duo, comma-separated, no spaces:

python pdb_selchain.py -A,C 1CTF.pdb
       # selects chains A and C

look at that. slayed. periodt. 👑

👑 THE pdb-tools LORE 👑

this program is part of the pdb-tools suite of utilities and should not be distributed isolatedly — fr fr, she does not travel alone, she's part of a friend group 🫂

the pdb-tools were created to quickly manipulate PDB files using the terminal, and they can be used sequentially, with one tool streaming data to another — like a little relay race of pipes, passing the file down the line 🏃‍♀️➡️🏃‍♀️➡️🏃‍♀️

they're based on old FORTRAN77 code that was taking too much effort to maintain and compile. RIP 😭💀 gone but never forgotten, truly the blueprint.

ngl if you made it this far you're lowkey a PDB main character now. no cap. 💅

mwah 💖 that was pdb_selchain version 2.5.1, dated September 2024 — stay hydrated, stream your chains responsibly, and see you in the next manpage bestie 🎀✨🦋
